Application filed June 23,

To @ZZ who/mt may concern.'

Be it known that I, Isaac J. lTA'r'rs, a citizen ot the United States,residing at King City, in the county ot Monterey and State otCalifornia, have invented certain new and useful Improvements in a BenchStop; and ido hereby declare the following to be a full, clear, andexact description ot the invention, such as will enable yothers skilledin the art t6 which it appertains to make and use the same.

This invention relates to a bench stop and it has t'or its primaryobject the provision ot a novel bench stop adapted to be applied to awoodworking bench and which may be easily and quickly adjusted forholding boards ot different thicknesses upon the bench while they arebeing planed.

Another object of the invention resides in the provision ot a bench stopot the character stated which comprises a plate adapted to be insertedin the upper surface of the bench and having a socket member dependingtherefrom and a slidable stop member adapted to be locked at differentpositions within the socket member after being adjusted therein, thelocking means including a gear which rests within a socket in the upperplate of the stop member. Y

lVith the 'foregoing and other objects in view, as will appear as thedescription proceeds, the invention consists in the novel construction,combination and arrangement of cooperating elements as hereinafter morespecifically set forth, claimed and shown in the accompanying drawingsforming a part ot' the present application and in which:

Figure l is a top plan view ot the bench stop,

Figure 2 is a vertical transverse sectional view of the same on theplane of line 2-2 ot Figure l.

Figure 3 is a horizontal sectional view on the plane ot line 3-3 oflFigure 2, looking in the direction indicated by the arrows.

Figure elis a transverse vertical section through a modiiied form of theinvention.

Referring more in detail to the drawings, in which similar referencecharacters designate correspondingparts throughout the several views, lindicates the securing or supporting plate which is adapted to be se.-cured in a suitable opening provided therefor in a work bench, bysuitable securing members l as through the corner portions Specificationof Letters Patent.

ot the plate l. A socket member 3 depends Jfrom the plate l and has aplurality of inwardly directed teeth 4 formed on the inner tace ot thetransversely curved wall thereof which connects two of the parallelwalls at one longitudinal edge. The remaining longitudinal edges ot theparallel walls ot' the sockets 3 are connected by the straight verticalwall opposite the transversely curved wall as clearly shownA in thedrawings. The vplate l is provided in its intermediate or centralportion with an opening 2 having beveled* end walls 2 so as toaccommodate the upper flat portion or main portion ot the stop member 5so that the upper face thereot will be iush with the upper tace of theplatel when the stop member 5 is in its lowermost position and restingon the walls 2 ot the opening 2 in the plate l. The stop member 5 isprovided with serrations 6 on one edge against which the board is to beplaced 'when the same is held in position upon the work bench. The stopmember is provided in its upper side with a recess 7, the purpose ofwhich will presently appear.

A depending guide 8 of substantially U- shape form in cross section iscarried by the stop member 5 and adapted to ride in the socket 3depending from the plate l. A transverse bar 8 is carried in the lowerend of the depending guide. 8 and forms a bearing for the lower end ofthe locking bolt 9 which is extended therethrough and has a washer 9 orthe like secured upon its lower extremity beneath the bar 8 so as tohold the locking bolt 9 in locking position, The locking bolt 9 has alaterallyY extended linger or arm 11 provided with af central notch l2tor accommodating one of the teeth et when the locking bolt 9 is innormal position. The spring l0 is coiled around the locking bolt 9 andhas one end secured to the finger or arm 11 while its opposite end issecured to the lower face of the top member 5, as clearly shown inFigure 2 of the drawings, thereby resiliently retaining the finger orarm 1l in operative engagement or locking engagement with one of theteeth 4. It will also be seen that the upper end of the locking bolt 9is extended centrally through the stop member 5 and then bent at a rightangle to terminate in a tapering and horizontally curved releasing endwhich rests in the recess 7 and is adapted to be swung therein as willbe later apparent. A thumb accommodating recess 14 is also provided atone side edge of the recess 7. It will therefore be seen that as thethumb of the operators hand rests in the recess 14, the :fourth lingerof the same hand may be engaged with the releasing end 13 of the lockingbolt 9 toswing the latter' toward the .recess 14, thereby turning` thelocking bolt 9 so as to swing the finger or arm 11 thereof away from thetooth bar with which it is engaged `and permit the stop member with theguide 8 thereof to be adjusted longitudinall y or vertically withrespect to the upper face of the work bench. As soon as the releasingend 13 is released, the spring 1() will serve to return the locked bolt9 to operative position and thereby look the linger or arm. 11 of thelocking bolt 9 with one of the teeth l to prevent further movement ofthe stop member 5 and thel depending guide 8 thereof.

In Figure et of the drawings I have shown a modilied form of theinvention in which the recess 7 is of a slightly different form and alocking lever 15 is employed in place of the locking bolt 9. The lockinglever 15 extends upwardly within the guide 8 and is mounted at itsintermediate enlarged portion 1G on a transverse pivot pin 17 carried bythe guide 8. The lever 15 has its lower end 1S curved slightly andterminates in an angularly extended locked finger 19 adapted to beengaged between two of the locking teeth 4 formed on the inner face ofone wall of the depending socket member B-but which wall in this casemay be in the form of a straight vertical wall, thereby providing asocket member which is of substantially rectangular form in crosssection. The upper portion of the lever 15 is extended through a centralelongated slot 2O in the stop member 5 and terminates in a finger grip21 by means of which the lever 15 may be readily operated to withdrawthe locking linger 19 thereof :from engagement with the teeth Ll. Assoon as the finger grip is released, however, the locking lever 15 willbe automatically returned to operative `posit-ion by the means of thespring 22 having one end con nested with the upper portion of the lever15, above the pivot pin 17 for the lever 15, while the opposite end ofthe spring 22 is connected with one wallpof the extending guide 8, asclearly shown in the drawings.

It `is believed that the complete construction and operation as well asthe advantages of the present invention may be readily7 understood fromthe foregoing paragraphs taken in connectionwith the accompanyingdrawings without further detailed description. Y

l/Vhile the preferred embodiment of the invention has been shown anddescribed, it will be understood that minor changes in the ldetails ofconstruction and arrangement of parts may be resorted to within thescope of what is claimed without departing from the spirit of theinvention.

1. A bench stop providing a socket member provided with retaining meanstherein, a guide member slidably mounted in the socket member, a stopplate on said guide member capable of disposition in its Lipper surfacefiush with the upper surface of the socket member, said plate having Aarecess in fits upper surface, a key journaled in said plate, said keyhaving ahead adapted to engage said retaining means, said key at theouter endV having an angular extremity disposed in ,said recess belowthe upper surface of the stop plate, and a spring secured to the stopplate and the key tensioned to normally maintain the key in engagementwith ysaid retaining means.

2. A bench stop comprising a socket ineinber having teeth locatedtherein, a guide movably mounted in said socket member, a stop platecarried by said guide, a looking lever pivotally mounted in said guide,a locking nger extended from said lever for engagement with certain 4ofsaid teeth, one end of said lever projecting through said stop plate,and means to resliently maintain said locking lever in operativeposition.

In testimony whereof I atlix my signature in presence of two witnesses.
